The bike mentioned is from the Admiralty contract C/S 13872 with frame numbers WB30 601-700...

The majority of B30 'survivors' are from that contract, some of the contract were sent to Malta with one recorded as having been recovered from Singapore...

The contract is mentioned in both editions of O & M but 'C' numbers are not noted..As an Admiralty contract they would probably have had an 'RN' prefix in most cases....

My own B30 was from that contract and at the time no serial numbers were available from the records..Employing a dose of 'artistic license' I put mine into 1st Royal Marine Engineers markings....Ian
